It depends on what is considered a "re-shoot." General reshoots are budgeted - things that come up in the edit. They need a pick-up shot here, a better angle there, or a transition to fit the story. Those are budgeted and written into talent contracts. Then you have situations like Indy and to a greater extent, Solo, where the studio realizes a significant issue in production or in test screenings where they have to fire creatives, re-write scripts and re-shoot the film, or the third act. That's where budgets spiral out of control and why reports saying Indy's budget was only $250 million miss the entirety of what was spent on production, which reached north of $300 million. Take the $300 million production budget, add $100 to $150 million for marketing and associated costs, and you get the real numbers. That's been Disney's real issue (in addition to who they have running things at LFL and their writers) - they are spending too damn much for these tent pole movies.
